Why You Might Be Wasting Money on Microsoft 365 By Using The Wrong Licences
Here’s a fun fact: Most SMEs are overspending on their Microsoft 365 licences — often by thousands per year. And the worst part? They don’t even know it.
Between confusing product names, subtle feature differences, and constant new SKUs popping up like whack‑a‑moles, Microsoft has created a licencing maze that even seasoned IT managers find annoying.
But here’s the good news: with a bit of clarity (and some honest advice), you can cut costs, simplify your setup, and avoid paying for features your staff will never use.
💸 Why SMEs Commonly Overspend on M365
1. They buy what they’ve “always had”
Legacy licencing decisions carry on for years, even after a business’s needs have changed.
2. Microsoft’s naming conventions are… creative
Business Standard, Business Premium, E3, E5, F3, Apps for Business, Apps for Enterprise — it’s confusing on purpose.
3. Vendors often overspec “just in case”
We’ve seen companies pay for E5 licences for users who only send emails and open Excel twice a week. (Honestly, it should be illegal.)
4. Businesses don’t understand the security stack
Many SMEs pay for:
- Third‑party email filtering
- Third‑party mobile device management
- Third‑party identity protection
…while also paying for M365 licences that already include these features.
5. They don’t offboard unused accounts properly
We’ve audited tenants with dozens of paid licences assigned to old employees, contractors, and test accounts. Money. Down. The. Drain.
🔍 The Biggest M365 Licensing Mistakes We See in the Real World
Here are the classics:
🚫 Mistake #1: Buying E3 or E5 “because it sounds better”
E5 is powerful — but most SMEs don’t use:
- Advanced audit
- Microsoft Defender for Identity
- Purview Insider Risk
- Advanced eDiscovery
- Calling plans
SMEs often only need Business Premium + add‑ons.
🚫 Mistake #2: Paying for mobile management tools despite having Intune
If you have Business Premium, Intune is included. You shouldn’t be paying for another MDM platform unless you have a very niche use case.
🚫 Mistake #3: Using Business Standard for users who need conditional access
Business Standard does NOT include key security features like:
- Conditional Access
- Device Compliance
- Intune
- Defender for Business
This creates security holes AND costs more when you inevitably bolt on other tools.
🚫 Mistake #4: Giving every user the same licence
Not every role needs the same features!
Common optimisation approach:
- Business Premium → security‑sensitive staff
- Business Standard → regular office workers
- F3 → frontline / warehouse / factory floor staff
- Shared mailbox → users who left or generic mailboxes (FREE!)
Proper segmentation = massive savings.
🧠 What SMEs SHOULD be doing in 2026
Here’s how to stop wasting money and actually get the right licences:
1. Audit your entire tenant
Check:
- Who has what licence
- Whether they still work there
- Whether they need the features
- Whether add‑ons are duplicated
We can do this in minutes.
2. Map licences to real job roles
Break down access needs:
- Do they need advanced security?
- Do they use desktop Office apps?
- Do they need shared device support?
- Do they need Teams Phone?
3. Remove unused licences immediately
If you’re paying for unassigned licences, you’re paying for nothing.
4. Use annual commit licences strategically
For long‑term staff: annual commit.
For temps/contractors: monthly flexible licencing.
This alone stops unnecessary waste.
5. Leverage Business Premium properly
Business Premium includes:
- Intune
- Defender for Business
- Conditional Access
- Azure AD Premium features
- Endpoint vulnerability management
If you use it fully, you can eliminate:
- Third‑party MDM
- Some third‑party MFA tools
- Some third‑party VPN solutions
Massive savings available here.
🏦 Real Example: How One SME Saved £8,000/year
(Composite example based on typical customer scenarios)
They were running:
- 40 × E3
- 20 × Business Standard
- 3 × E5 “for IT”
- Third‑party mobile device management
- Third‑party email phishing tool
After a full optimisation:
- 45 × Business Premium
- 15 × F3
- Remove MDM
- Switch phishing tool to integrated solution
Total savings: £8,000 per year.
This is extremely common.
